mea s of a u q c c e having a portion In order that the shell l5 may be collapsible projecting outwardly of the casing for actuation it is formed with longitudinal corrugations l1 and a sealing member of novel construction 00- in the sides and a corrugation l8 around the operating with the winding and setting means head It. As a result, the stem l2 though brazed to permit actuation thereof and at the same to the shell I5, is free to be reciprocated to effect 55 a winding of the watch. Preferably the natural tendency of the shell i 5 to return to its expanded position, shown in Fig. 2, is aided by a leaf spring 59 interposed between the casing and the stem to urge the latter outwardly; Thus, it' is seen that by the employment of a winding means and a sealing means of the character described the stem 52 is in effect completely enclosed and thus prevents any moisture from entering the casing around the stem.

Ihe setting means, like the winding means, comprises a stem 26 projecting through the side edge of the central ring 3, opposite the stem i2, and guided thereby for axial reciprocation. At its inner end the stem 2i carries a pawl spring pressed into engagement with a toothed wheel 22. In order that an accidental reciprocation of the stem 26 may not change the setting of the watch, the wheel 22 is not permanently connected to the hands of the watch but is connected or disconnected by means of a clutch 23 controlled by a third'stem 2d. Accordingly, the wheel 22 is freely rotatable on a shaft 25 and carries a'clutch element 26. Reciprocable axially of the shaft 25 but fixed against relative rotation therewith is a cooperating clutch element 21. This element is connected to the inner end of the stem 25 by a pair of toggle links 28 arranged to cause engagement of the clutch ele ments when the stem 24 is pressed inwardly. The shaft 25-is connected in any well known and suitable manner, not shown, to the hands of the watch.

Secured and sealed to the casing I and to the stems 2H and 2- 5 is a collapsible shell 29. With the exception of a transverse corrugation or partition 36 provided to permit opposite halves of the shell to have an independent collapsing movement, the shell 29 is identical with the shell I5 so that the symmetry of the watch is not destroyed. A leaf spring 3! is also provided for each of the stems 2t and 2s urging the same outwardly and the stems terminate in a head 32 and 33 respectively. Thus to set the watch, the stem 24 must be held in its inward position while the stem 26 is reciprocated. Any accidental setting is thereby effectually precluded.

I claim as my invention:

1. In a watch a casing enclosing operating parts of the watch, the parts of said casing being assembled in a water-tight relationship, means including a reciprocable member for winding the main spring of the watch, a stem projecting through a wall of said casing and operable to actuate said reciprocable member, and a hollow member secured to said casing over the place of projection of said stem to seal the casing against moisture and collapsible to permit operation of the stem. I

2. In a watch having a casing with the parts thereof fitted together to form water-proof joints, a stem projecting from within the casing and reciprocable axially to wind the watch and a collapsible member connected to said stem and to the casing around the stem to form a waterproof seal preventing moisture from entering the casing around the stem.

3. In a watch having a casing, the parts of which are assembled in water-tight relationship, means for winding the main spring of the watch comprising an axially reciprocable stem projecting outwardly through one edge of the easing, a toothed wheel geared to the main spring and a pawl actuated by reciprocation of said stem to rotate said wheel, and a collapsible metallic shell secured to the edge of the casing around the stem to seal the casing against the entrance of moisture around the stem.

i. In a watch having operating mechanism and a casing therefor the parts of which are assembled in a water-tight relationship, an axially reciprocable stem projecting from within the casing, said stem having an engagement with a part of the mechanism and operable upon reciprocation to actuate the same, a. metallic sealing shell attached to the casing in watertight relationship over the place of projection of said stem and attached in water-tight relation to the stem near the outer end thereof, said shell being collapsible to permit reciprocation of said stem, and a spring urging said stem outwardly of the casing.

5. In a watch, the combination of a casing for enclosing the works of the watch, the parts comprising thecasing being assembled in watertight relationship, an axially reciprocable stem projecting from within the casing and oper- 6. In a watch having operating mechanism ineluding hands, a casing therefor the parts of which are assembled in water-tight relationship, an axially reciprocable stem projecting outward ly of the casing, a wheel adapted to be rotated by reciprocation of said stem, a clutch operable to connect said wheel to the mechanism to set the hands, a second axiallyreciprocable stem projecting outwardly of the casing and controlling the clutch, and a collapsible metallic shell connected to'the casing around said stems to seal the casing against the entrance of moisture around the stems. M

'7. In a watch having operating mechanism including hands, a casing therefor the parts of which are assembled in water-tight relationship, means for setting the hands comprising an axially reciprocable stem projecting outwardly of the casing, means including a clutch for connecting said stem to the hands, a second stem projecting outwardly of the casing and axially reciprocable to control the clutch, said stem being urged in a direction to disconnect the hands and the first mentioned stem, and a sealing device attached to the casing around said stems and collapsible to permit reciprocation of the stems.

8. In a watch having a casing, the parts of which are assembled in water-tight relationship, a pair of axially reciprocable stems projecting outwardly of the casing along the same side edge and an elongated collapsible metallic shell mounted over the side edge and connected to the casing and to the stems in water-tight relation, said shell having .a transverse partition intermediatecthe points of attachment to the stems to permit independent collapse of the portions of the shell.
